aprendizado decorrente de uma ação de conscientização: como a atividade prática impactou alunos do curso de Medicina
by Cesar Augusto Machado de Moraes, Amanda Paixão Rampinelli, Anna Clara Demarques Dourado, Giovana Felicio Gomes Pedroso, Henrique Cian da Cruz, Julia Mitiko Miyoshi, Louise Muricy Doetzer, Luísa Benincá Trentini, Maria Fernanda Américo de Oliveira, Mylena Campos Weyand, et al.
INTRODUÇÃO: Diante da densa grade curricular, a inserção do aluno de Medicina na comunidade, logo no início do curso, é de suma importância para sua formação, visto que é por meio dessa inserção que o aluno é exposto às problemáticas presentes na realidade da comunidade. A disciplina de Interação Comunitária propôs aos alunos do primeiro ano que realizassem uma ação educativa acerca das doenças crônicas mais prevalentes, a saber, o Diabetes e a Hipertensão Arterial Sistêmica. Portanto, o presente relato de experiência traz as observações conferidas pelos autores antes, durante e após a realização da ação de conscientização no campus da universidade no ano de 2021, e a importância da atividade prática para a consolidação do conhecimento. RELATO: A ação educativa ocorreu em novembro de 2021. Os autores deste trabalho se responsabilizaram por expor à comunidade indicadores de saúde e doença relacionados com as condições crônicas referidas anteriormente. Optou-se, então, em aferir a glicemia capilar, a pressão arterial, a realizar o cálculo do IMC e a distribuir cartilhas contendo informações gerais e os valores de referência para os exames realizados. DISCUSSÃO: Fica evidente que as atividades extracurriculares proporcionam a inserção dos acadêmicos em cenários médicos com a participação em atenção à saúde de pessoas reais como forte componente de aprendizado profissional. A relação do aluno com a comunidade o prepara para lidar com o paciente de uma forma humanizada, que vai além do tratamento farmacológico. CONCLUSÃO: O resultado geral dessa ação social foi uma somação de aprendizado que se irradia para todos os envolvidos: os alunos amadureceram quanto ao processo de aprendizagem, e os voluntários receberam informações sobre seu estado de saúde.

Rayleigh-Brillouin scattering in binary mixtures of disparate-mass constituents: ${SF}_{6} − He, {SF}_{6} − D_{2}$ , and ${SF}_{6} − H_{2}$
by Yuanqing Wang, Wim Ubachs, Cesar A. M. de Moraes, Wilson Marques
The spectral distribution of light scattered by microscopic thermal fluctuations in binary mixture gases was investigated experimentally and theoretically. Measurements of Rayleigh-Brillouin spectral profiles were performed at a wavelength of 532 nm and at room temperature, for mixtures of ${SF}_{6} − He, {SF}_{6} − D_{2}$ , and ${SF}_{6} − H_{2}$ . In these measurements, the pressure of the gases with heavy molecular mass $({SF}_{6})$ is set at 1 bar, while the pressure of the lighter collision partner was varied. In view of the large polarizability of ${SF}_{6}$ and the very small polarizabilities of He, $H_{2}$ , and $D_{2}$ , under the chosen pressure conditions these low mass species act as spectators and do not contribute to the light scattering spectrum, while they influence the motion and relaxation of the heavy ${SF}_{6}$ molecules. A generalized hydrodynamic model was developed that should be applicable for the particular case of molecules with heavy and light disparate masses, as is the case for the heavy ${SF}_{6}$ molecule, and the lighter collision partners. Based on the kinetic theory of gases, our model replaces the classical Navier-Stokes-Fourier relations with constitutive equations having an exponential memory kernel. The energy exchange between translational and internal modes of motion is included and quantified with a single parameter $z$ that characterizes the ratio between the mean elastic and inelastic molecular collision frequencies. The model is compared with the experimental Rayleigh-Brillouin scattering data, where the value of the parameter $z$ is determined in a least-squares procedure. Where very good agreement is found between experiment and the generalized hydrodynamic model, the computations in the framework of classical hydrodynamics strongly deviate. Only in the hydrodynamic regime both models are shown to converge.

Understanding the effect of solvent additive in polymeric thin film: turning a bilayer into a bulk heterojunction-like photovoltaic device
by Leandro Benatto, J A Govatski, Cesar Augusto Machado Moraes, Cristol Paiva Gouvêa, Harold Camargo Avila, Cleber Fn Marchiori, Camila Karla Brites Queiroz Martins Oliveira, Marco Cremona, Marlus Koehler, L S Roman
Here we report the effect of an additive solvent, 1,8-diiodooctane (DIO), on the performance of a bilayer organic photovoltaic device in which the active layer comprises poly[2,7-(9,9-bis(2 ethylhexyl)-dibenzosilole)-alt-4,7-bis(thiophen-2-yl)benzo-2,1,3-thiadiazole] (PSiF-DBT) as the electron donor material and C ₆₀ as the electron acceptor material. We observed that when the donor layer was treated with 1% of DIO the power conversion efficiency (PCE) of the device increased by 138.4% in relation to the device with an untreated donor layer, and 21.3% in relation to the device containing a donor layer submitted to thermal annealing. The main effects that lead to this increase in PCE are the large interfacial area between donor and acceptor materials and the improved conductivity at low voltages. The increase in polymer surface roughness leads to a more effective PSiF-DBT/C ₆₀ interface for exciton dissociation. This effect, as well as the increase in the conductivity, raised the short circuit current density ( J _SC ) to 13.89 mA cm ⁻² and the PCE to 4.84%. Our conclusions are supported by morphological analysis, chemical cross-sectional evaluations with advanced microscopy techniques, charge mobility measurements, as well as by theoretical simulations of the devices in which the changes on the donor/acceptor interfacial area were considered. The outcomes suggest that solvent additives could be an alternative treatment to replace the thermal annealing, which imposes further difficulties in performing lab-to-manufacturing upscaling.
